As shown in FIG. 5, the power source stem 95 includes a cylindrical power source stem sleeve 951, an absorption stem connector 7 disposed at one end of the power source stem sleeve 951, a base cover 953 disposed at the other end of the power source stem sleeve 951 for enclosing the sleeve 951, a battery 954 positioned in the power source stem sleeve 951, a control component 955 and a control component bracket 956. In the electronic cigarette 100, the absorption stem sleeve 1 and power source stem sleeve 951 constitute the aforementioned electronic cigarette enclosure 81. The power source stem sleeve 951 is made of the same material as the absorption stem sleeve 1. A paper layer 952 identical to the paper layer 17 is also provided on the outer wall of the power source stem sleeve 951. The paper layer 952 is a cylinder matched with the power source stem sleeve 951. The paper layer 952 is sleeved on the outer wall of the power source stem sleeve 951 so that the power source stem sleeve 951 is wrapped by the paper layer 952.

The absorption stem connector 7 is intended for connection with the absorption stem 90 and is composed of a connection bushing 71, a power source electrode member 72 and an insulation ring 73. The connection bushing 71 is of a cylinder shape and its outer wall is tightly pressed against and secured on the inner wall of the power source stem sleeve 951. The inner wall of the connection bushing 71 is provided with an internal thread and a holding groove for holding the power source electrode member 72. The power source electrode member 72 is sleeved on the middle portion of the connection bushing 71 by the insulation ring 73. The power source electrode member 72 and connection bushing 71 are respectively electronically connected to the positive and negative electrodes of the battery 954. An intake hole is defined in the base cover 953 permitting entrance of external air into the power source stem 95. The control component 955 is used for control operation of the entire electronic cigarette and is provided with a mini pneumatic switch for control conduction of the electric circuit such that the electronic cigarette starts to work.
